A leading freeze drying machines manufacturer in China, from lab pilot to industrial production freeze dryers.

Tray Bulk Freeze Dryer

FDL Tray Freeze Dryer

An Economic Freeze Drying Solution For Bulk Material

The Vikumer FDL tray Freeze dryers are versatile apply in pharmaceutical, biological, chemical and food fields. Meet freeze drying demand of bulk material include solid, liquid, paste, powder or granular shape.

Raw product loaded in trays and placed in drying chamber, the machine will automatically freeze it, vacuumize the drying chamber and later apply heat to it enable sublimating and drying.

Designed keep in mind of versatility and multi-function, the FDL lyophilizers are high automation. Automatic freeze drying from start to end, from raw product freezing to drying end.

To accommodate the high production capacity between commercial and industries. The FDL lyophilizer trays area up to 55 square meters, coupling with condenser capacity up to 1000kgs in 24hrs cycle.

Superior Craftsmanship

  • Drying chamber and condenser are designed according to GB150 pressure vessel code and are fabricated from high quality stainless steel, inner surface fine polish Ra<0.4um. Internal components go through special treatment, no chipping, no distortion while huge temperature difference between freezing stage and sublimation stage.

Precise temperature control and uniformity guarantee

  • The rectangular drying chamber with PUF insulation layer is very good to control the temperature uniformity. Plus the delicate designed shelves energy balance system, can guarantee plates temperature variance <+/-1C, which is the insurance of high freeze dried quality.

Efficient Design

  • Plates heating and chilling rate >1C/min, enables flexible program freeze drying steps.

Fully Automatic Freeze Drying

  • The touch screen enables operator flexible program freeze drying steps; system can store hundreds of freeze drying recipes. Freeze dry system work as per settings, one step finish, another automatic start, until drying end.
